Solution Overview
Problem
Current methods for controlling unmanned aerial vehicle (UAV) flight status require administrators to return to a monitoring computer, making the process inefficient and inconvenient.
Innovation Solution
An electronic device equipped with a storage device, UAV control system, accelerometer, signal projector, and processor allows users to control UAV flight status through movement data detected by the accelerometer, converting it into control signals to change the UAV's flight status wirelessly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UAV control is performed through a monitoring computer, then control functionality is available, but operational efficiency deteriorates due to the need to return to the monitoring computer for status changes
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the operator and the UAV control system. The mobile device receives control inputs from the user and transmits them to the UAV, eliminating the need to return to the monitoring computer. This intermediary device enables efficient on-the-go control while maintaining the existing UAV control system architecture.
Solution Approach 2:
The patent adds a new spatial dimension for control by enabling UAV status changes through mobile devices outside the monitoring computer environment. This allows operators to control UAV flight status from any location with mobile device connectivity, transforming the control interaction from a fixed-location operation to a mobile, location-independent operation.
2Productivity
If a mobile device with accelerometer is used for control, then control efficiency improves, but device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The mobile device leverages its existing self-service capabilities including built-in accelerometer, processor, and communication interfaces. Rather than adding external complexity, the invention utilizes the mobile device's inherent sensors and processing power to detect movement, convert it to control signals, and transmit commands to the UAV, making the mobile device self-sufficient for control operations.
Solution Approach 2:
The patent makes the mobile device serve multiple functions: it acts as a control input device through accelerometer-based movement detection, a signal processing unit for converting movement to control commands, and a communication interface for transmitting signals to the UAV. This multi-functionality reduces the need for dedicated specialized equipment, thereby managing complexity while improving efficiency.
